Domesday, or Doomsday

The name Domesday Book -
Doomsday in earlier spellings - was first recorded almost a century
after 1086. An addition to the Domesday manuscript probably made between
1114 and 1119 calls it the Book of Winchester.
Between that date and 1179, it acquired the name by which it has since
been known. No less a person than the Treasurer of England recorded then
that 'This book is called by the native English Domesday, that is Day
of Judgement' (Dialogus de scaccario (1950), page 64; (1977), pages 96-99). Like the Last Judgement, the treasurer explained, the decisions of Domesday Book were unalterable: 'as from the Last Judgement, there is no further appeal'.
